Question 381

In which type of cloud model are all the hardware resources owned by a third-party and shared between multiple tenants?

A. private
B. hybrid
*C. public

Explanation

Microsoft Azure, Amazon Web Services and Google Cloud are three examples of public cloud services.

Microsoft, Amazon and Google own the hardware. The tenants are the customers who use the public cloud services.

Question 382

An Azure web app that queries an on-premises Microsoft SQL server is an example of a __________ cloud.

*A. hybrid
B. multi-vendor
C. private
D. public

Explanation

You can deploy hybrid app with on-premises data that scales cross-cloud.

Question 383

Instructions: To answer, drag the appropriate benefit from the column on the left to its description on the right. Each benefit may be used once, more than once, or not at all.
NOTE: Each correct match is worth one point.

Answer Options:

• Disaster recovery
• Fault tolerance
• Low latency
• Dynamic scalability

Answer Area:

• A cloud service that remain available after a failure occurs.
• A cloud service that can be recovered after a failure occurs
• A cloud service that performs quickly when demand increases.
• A cloud service that can be accessed quickly from the Internet.

Answer:
Disaster recovery: A cloud service that can be recovered after a failure occurs
Fault tolerance: A cloud service that remain available after a failure occurs.
Low latency: A cloud service that can be accessed quickly from the Internet.
Dynamic scalability: A cloud service that performs quickly when demand increases.

Explanation

Fault tolerance is the ability of a service to remain available after a failure of one of the components of the service. For example, a service running on multiple servers can withstand the failure of one of the servers.

Disaster recovery is the recovery of a service after a failure. For example, restoring a virtual machine from backup after a virtual machine failure.

Dynamic scalability is the ability for compute resources to be added to a service when the service is under heavy load. For example, in a virtual machine scale set, additional instances of the virtual machine are added when the existing virtual machines are under heavy load.

Latency is the time a service to respond to requests. For example, the time it takes for a web page to be returned from a web server. Low latency means low response time which means a quicker response.

Question 384

To implement a hybrid cloud model, a company must have an internal network.

A. Yes
*B. No

Explanation

A company can extend the computing resources of its internal network by using the public cloud. This is very common. When you need more resources, rather than pay out for new on-premises infrastructure, you can configure a cloud environment and connect your on-premises network to the cloud environment by using a VPN.

Question 385

A Platform as a Service (PaaS) solution provides full control of operating systems that host applications.

A. Yes
*B. No

Explanation

A PaaS solution does not provide access to the operating system. The Azure Web Apps service provides an environment for you to host your web applications.
Behind the scenes, the web apps are hosted on virtual machines running IIS. However, you have no direct access to the virtual machine, the operating system or
IIS.

Question 386

A Platform as a Service (PaaS) solution provides additional memory to apps by changing pricing tiers.

A. Yes
*B. No

Question 387

A Platform as a Service (PaaS) solution can automatically scale the number of instances.

*A. Yes
B. No

Question 388

Paying electricity for your datacenter is an example of OpEx.

A. Yes
*B. No

Explanation

Paying for electricity for your own datacenter will be classed as CapEx, not OpEx.

Question 389

To which cloud models can you deploy physical servers?

*A. private cloud and hybrid cloud only
B. private cloud only
C. private cloud, hybrid cloud and public cloud
D. hybrid cloud only

Explanation

A private cloud is on-premises so you can deploy physical servers.
A hybrid cloud is a mix of on-premise and public cloud resources. You can deploy physical servers on-premises.

Question 390

Match the cloud model to the correct advantage.
Instructions: To answer, drag the appropriate cloud model from the column on the left to its advantage on the right. Each cloud model may be used once, more than once, or not at all.
NOTE: Each correct match is worth one point

Cloud model:

• Hybrid Cloud
• Private Cloud
• Public Cloud

Work Area:

• No required capital expenditure.
• Provides complete control over security.
• Provides a choice to use on-premises or cloud-based resources.

Answer:

• Hybrid Cloud: Provides a choice to use on-premises or cloud-based resources.
• Private Cloud: Provides complete control over security.
• Public Cloud: No required capital expenditure.

Explanation

Hybrid Cloud: A hybrid cloud is a mix of public cloud resources and on-premises resources. Therefore, you have a choice to use either.
Private Cloud: A private cloud exists on premises, so you have complete control over security.
Public Cloud: With a public cloud, there is no capital expenditure on server hardware etc. You only pay for cloud resources that you use as you use them.
